Imo DoW has an easier time for drops due to them only fighting for drops against other tanks and melee dps.
But usually u get a few blms and since both healers r casters it's almost free loot.
Especially if you run in a premade where its the 1 tank method.
Casters get the end of the stick here also it kinda proves my point as se decides to just recolour the caster robe. Why? We'll never know.
